High cholesterol diets modify gene expression in atherosclerosis
Scientists from the department of Biochemistry and Molecular Biology 1 of the University of Granada (Universidad de Granada) have proven that a high cholesterol diet causes changes in gene expression of chicken aortic smooth muscle cells at the early stages of an experimental atherosclerosis. view more (2007-06-13)
At petting zoos, simple disease prevention guidelines frequently ignored
A new study shows that simple guidelines to protect petting zoo patrons from disease-causing germs found in the zoo are frequently not followed, thus allowing the risks of contracting serious intestinal illnesses to persist. view more (2007-06-12)

Reproductive speed protects large animals from being hunted to extinction
The slower their reproductive cycle, the higher the risk of extinction for large grazing animals such as deer and antelope that are hunted by humans. view more (2007-05-16)
Scientists develope a new model of artificial canine skin
Researchers at UNIVET, a spin-off of the Universitat Autònoma de Barcelona, in cooperation with the animal nutrition company Affinity Petcare, have developed an artificial cellular model which faithfully reproduces the characteristics of dog's skin and which will allow, therefore, the carrying out of various lines of research related to... view more...

Correlation between bile duct obstruction and ductal cancer found
When bile duct cancer cells were placed in the liver of animals with bile duct obstruction, they grew more rapidly than identical cells placed in animals without bile duct obstruction. view more (2007-04-30)
Does a peptide affect the heart's response to social isolation?
A team of researchers investigating the effects of oxytocin, a peptide produced by the brain that regulates social behavior, has found that it can prevent detrimental cardiac responses in adult female animals exposed to social isolation. The findings may provide further insight into how these mechanisms affect humans. view more (2007-04-30)
How dogs don't ape
A distinguishing feature of human intelligence is our ability to understand the goals and intentions of others. This ability develops gradually during infancy, and the extent to which it is present in other animals is an intriguing question. view more (2007-04-27)
Mosquito genes explain response to climate change
University of Oregon researchers studying mosquitoes have produced the first chromosomal map that shows regions of chromosomes that activate - and are apparently evolving - in animals in response to climate change. view more (2007-04-24)
University of Alberta researchers unravel intricate animal patterns
There is a scene in the animated blockbuster "Finding Nemo" when a school of fish makes a rapid string of complicated patterns—an arrow, a portrait of young Nemo and other intricate designs. view more (2007-04-17)
